He very well may be but how many times have we all seen a backup player on another team go to a new team and look like an entirely different player? The 1st thing I thought of when just before the OTA's last year when the Cowboys announced they were moving Collins to RT was when Collins came to the Cowboys Free was rehabbing an injury and they tried Collins at RT and determined that he was a guard in the NFL. So they played him at guard all through training camp and when Leary suffered a pulled groin in week 1 Collins went in and played LG until week 16 when he got injured. This was 2015 and it was Collins best year as a pro. He was a far better LG than he was at RT last season so I'm in favor of moving Collins back to LG and finding another LT.
.
when collins came to cowboys, free was the senior statesman who may have gotten a priority over collins.
lord knows, we kept free for a year or two too much because he was some type of ol leader despite.
if fleming was a decent starter, i would suspect patriots would have tried keeping him the year before.
collins was lt in college and most expected to him as a rt, not g.
that means he has certain measurables that fleming probably lacks.
my guess is his agility which you need for ot play.
